Description

알루미늄을 이용한 무선 주파수 식별카드{Radio frequency identification card of using aluminum}Radio frequency identification card of using aluminum

본 발명은 무선 주파수 식별(radio frequency identification : RFID)카드(Card)에 관한 것으로, 더욱 상세하게는 무선 주파수 식별 카드에 동선으로 메모리 칩과 연결된 안테나를 알루미늄 선을 이용하여 연결함으로써 접촉을 용이하게 하고 가격을 저렴하게 할 수 있는 알루미늄을 이용한 무선 주파수 식별카드이다.The present invention relates to a radio frequency identification (RFID) card, and more particularly, to facilitate contact by connecting an antenna connected to a memory chip with a copper wire using an aluminum wire. It is a radio frequency identification card using aluminum, which can reduce the price.

무선 주파수 식별카드는 비접촉식 카드(Contactless Card)의 대표격이라 흔히 비접촉식 카드를 말할 때는 무선 주파수 식별카드를 일컫는다.A radio frequency identification card is a representative of a contactless card, so when referring to a contactless card, a radio frequency identification card is referred to.

무선 주파수 식별카드는 다른 접촉식 카드와는 달리 이용자가 카드를리더(Reader)에 삽입하는 시간이 필요하지 않으며 기계적인 접촉이 없기 때문에 마찰이나 손상이 없고 오염이나 환경의 영향이 적은 것이 특징이다. 안테나에서 지속적으로 전파를 발산하고 있고 아이디와 데이터가 저장된 카드(TAG)가 그 전파범위 안에 들어가면 자신이 지니고 있는 아이디와 데이터를 안테나로 전송한다.Unlike other contact cards, the radio frequency identification card does not require time for the user to insert the card into the reader, and there is no mechanical contact, so there is no friction or damage, and less pollution or environmental influence. When the antenna continuously emits radio waves and the card with the ID and data stored within the radio range, it transmits its ID and data to the antenna.

무선 주파수 식별카드는 감지거리가 길기 때문에 주차관리(Parking Control System)에 이용되며, 비금속 재료를 통과할 수 있어 유리, 섬유, 목재를 통과하여 카드를 주머니나 가방에 넣은 채로도 인식이 가능하다. 출입문 통과시 버스나 철도 이용시에 편리하다.Radio frequency identification cards are used for parking control systems because of their long sensing range. They can pass through non-metallic materials, allowing them to pass through glass, fiber, and wood, while still being recognized in the pocket or bag. It is convenient when using the bus or railway when passing through the door.

이런 무선 주파수 식별카드 안테나선은 일반적으로 동선을 이용하므로 메모리 칩과의 접합이 불량하게 되고, 회로 구성시 감광 필름을 사용함으로써 가격이 비싼 문제점이 있었다.Since the radio frequency identification card antenna line generally uses copper wires, the bonding with the memory chip becomes poor, and there is a problem that the price is expensive by using a photosensitive film in the circuit configuration.

본 발명은 상기와 같은 종래 기술의 제반 문제점을 해결하기 위하여 안출한 것으로 그 목적은, 무선 주파수 식별카드의 안테나부과 메모리 칩에 접합을 용이하게 하기 위하여 동선을 알루미늄 선으로 대체하여 감광액으로 디핑 처리함으로써 제조원가도 1/10 로 절감할 수 있는 알루미늄을 이용한 무선 주파수 식별카드를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems of the prior art, the object of the present invention is to replace the copper wire with an aluminum wire in order to facilitate bonding to the antenna portion and the memory chip of the radio frequency identification card by dipping with a photosensitive liquid The purpose of the present invention is to provide a radio frequency identification card using aluminum, which can reduce manufacturing costs by 1/10.

우선 알루미늄과 PET(PolyEthylene Terephthalate resin)(11)가 합지된 시트의 표면을 얇게 탈취, 표면 처리하여 표면의 이 물질을 제거한 후, 감광액을 상기 합지된 시트에 필요한 두께로 디핑 처리한다. 상기 감광액으로 디핑된 시트를 건조시킨 후, 도안 필름과 같이 밀착하여 투시 프린터를 한다. 프린터된 상기 시트를 약품 처리하여 회로 패턴을 현상하고 부식작업을 통해 상기 회로 패턴을 제외한 전도체를 없앤다. 그 후, 디핑된 상기 시트에서 감광액을 벗겨내고 세정작업을 한다.First, the surface of the sheet on which aluminum and PET (PolyEthylene Terephthalate resin) 11 are laminated is lightly deodorized and surface treated to remove foreign matter from the surface, and then the photoresist is dipped to the thickness required for the laminated sheet. After the sheet dipped with the photosensitive liquid is dried, it is in close contact with a drawing film to produce a perspective printer. The printed sheet is chemically processed to develop a circuit pattern and to remove conductors except for the circuit pattern through corrosion. Thereafter, the photosensitive liquid is peeled off from the dipped sheet and cleaned.

이렇게 만들어진 상기 알루미늄 안테나는 13.56MHZ의 주파수 대역을 사용함 으로써 기존의 동선을 이용하여 125KHZ의 주파수 대역을 이용한 안테나보다 송수신의 오차범위를 줄일 수 있다.The aluminum antenna thus made can reduce the error range of transmission and reception by using a frequency band of 13.56MHZ by using an existing copper wire than an antenna using a frequency band of 125KHZ.
